啊哈算法


解密QQ - d
新学期开始了,小哈是小哼的新同桌(小哈是个小美女哦~),小哼向小哈询问QQ 号,
小哈当然不会直接告诉小哼啦,原因嘛你懂的。所以小哈给了小哼一串加密过的数字,同时
小哈也告诉了小哼解密规则。规则是这样的:首先将第1 个数删除,紧接着将第2 个数放到
这串数的末尾,再将第3 个数删除并将第4 个数放到这串数的末尾,再将第5 个数删除……
直到剩下最后一个数,将最后一个数也删除。按照刚才删除的顺序,把这些删除的数连在一

起就是小哈的QQ 啦。现在你来帮帮小哼吧。小哈给小哼加密过的一串数是“6 3 1 7 5 8 9 2 4”。

int main()
{
  int q[102]={0,6,3,1,7,5,8,9,2,4},head,tail;
  int i;
  //初始化队列
  head=1;
  tail=10; //队列中已经有9个元素了,tail指向队尾的后一个位置
  while(head<tail) //当队列不为空的时候执行循环
  {
  //打印队首并将队首出队
  printf("%d ",q[head]);
  head++;
  //先将新队首的数添加到队尾
  q[tail]=q[head];
  tail++;
  //再将队首出队
  head++;
  }
  getchar();getchar();
  return 0;
}

纸牌游戏——小猫钓鱼
星期天小哼和小哈约在一起玩桌游,他们正在玩一个非常古怪的扑克游戏——“小猫钓
鱼”。游戏的规则是这样的:将一副扑克牌平均分成两份,每人拿一份。小哼先拿出手中的
第一张扑克牌放在桌上,然后小哈也拿出手中的第一张扑克牌,并放在小哼刚打出的扑克牌
的上面,就像这样两人交替出牌。出牌时,如果某人打出的牌与桌上某张牌的牌面相同,即
可将两张相同的牌及其中间所夹的牌全部取走,并依次放到自己手中牌的末尾。当任意一人
手中的牌全部出完时,游戏结束,对手获胜。
